This invention relates to new and usei'ul improvements in stumppullers.A

An important object otthe invention is to provide a stump puller of veryrigid con- .s struction that is especially adapted tor extra heavy work.

A further object oi the invention is to provide a stump puller thatemploys an external source or' power, such as horses, a tractor, ora-truclr, -for operating the necessary mechanism to produce the verticalpull required to perform the work' the device is adapted for.

Other objects of the invention will be apparent during the course oi thefollowing description.

In the accompanying drawings formingY a partl ot this speciiicationandfin which like numerals are employed to' designate lilte'partsthroughout the saine,

Figure 1 is a side elevational view ot the stump puller embodying thisinvention,

Figure 2 is a top plan view orn the stump puller shown in Fig. 1,

Figure 3 is a longitudinal vertical sectional view taken upon linesIII-111 of Fig. 2, and v Figure d is a longitudinal horizontal sectionalview taken upon lines 1V -IV of Fig. 3.

1n the drawings, wherein for the purpose of illustration is shown apreferred embodiment of this invention, the numeral 5 designatesgenerally the pair ot parallel side frames each ot which consists ot abase bar 6 andan integrally formed upstanding end bar 7, there beingfurther provided a brace bar 8 which is formed integrally with the basebar 6 and end bar 7 and extends diagonally between the two. The parallelside frames 5 are suitably connected and retained in their proper spacedrelation to each other by the cross braces 9 y.which arel removablyconnected to the said side frames by the fastening elements 10. rlhereis further provided a rope guiding cross brace 11 which connects thebase bars in proximity to their points of connection with the upstandingend bars 7. These upstanding end bars are further provided with a ropeguiding cross brace 12, as best shown in Figs. 1 to 3 inclusive. Theserope guiding cross braces 11 and 12 are secured to the parallel sideframes by the fastening means 13. The opposite end of the base bars 6are provided with axles 14 and 15 which are adapted for hav- Serial No.637,985.

ing journaled thereon the ground engaging wheels which permit the stumppuller to be moved over the ground. rihe ends ot the base bars 6,associated with the upstanding end bars 7, are provided with laterallyinwardly projecting bars 1T which are adapted. for detachably receivingthe notched links 18 which are connected at their outer` ends to thecross pin 19 which carries the tongue 20. This tongue is provided with ablock 21 having a cutout portion 22 termed in its forward end thatreceives an externally threaded pin or bolt 23 ior the purpose ofconnecting the Whipple-tree portion of harness to the tongue `forenabling the stump puller to be drawn over the ground by horses or thelike.

The axle 14 has journaled thereon one end ot' the lever :9A: which isprovided with a sharpened projection 25 that extends outwardly ot' theperiphery ot the ground engaging wheels 16 and is adapted to be forcedinto engagement with a tree stump, such as is designated by the numeralQG in Fig. 1, for causing the said stump to be extracted when the innerend of the lever is pulled downwardly for forcing the sharpenedprojection 25 upwardly in respect to the ground. The tree end of thelever 24 is provided with an eye bolt '27 adapted to receive and beattached to one end ot the rope or cable 28. The lever 24 is furtherprovided with a bolt 29 having its head associated with the under faceof the same for engaging the cross brace 9 positioned therebeneath, whenthe lever 24 is'pivoted by drawing the free end downwardly toward thebase bar and upstanding end bars andV thereby acting as a stop forpreventing the' lever from engaging the operating mechanisin, carried bythe parallel side trames, which will be described at a later point.

For the purpose ot preventing the stump puller from being forced awayfrom the stump 26 when the lever 24 is pivoted upon the axle 14, theupper end of each upstanding end bar 7 is provided with a pivotallyconnected sprag bar 30 which may be positioned as shown in Figs. 1 to 3inclusive, for causing its outer end to engage the ground for preventingmovement of the puller away from the stump. r1`hese sprag bars, when notin use, may be swung on their pivot pins 31 to position their free endsupon the integrally formed supporting blocks 32 carried by the base bars6.

By referring particularly to Figs. 3 and i., it will be seen that thebrace bars S and upstanding ends bars T are provided with transverselyextending rotating shaft-s 33 and 3l and a stationary rod The rotatingshaft 325 is provided with a. grooved pulley 36 having sleeve extensions5T which are keyed, as at 23S, to the said sha'tt l'or causing thepulley to rotate therewith. The rotating shaft Si is lormed,intermediate its ends, with a squared portion 3S) which is adapted toreceive the drum il) which rotates therewith. ri`he projecting ends otthe rotating shafts 33 and it are provided with the pinion iil and meshyig gear l2 respectively. The opposite end ol' the shaft 3l orovidedwith a. crank handle i3 which may be employed for rotating the twoshafts and consequently the grooved pulley 36 and druni il). Thestationary sli-att has joarnaled thereon a grooved pulley it havinglaterally.l axially extending sleeves which are rotatal'ily mounted uponthe shaft 35.

It will be seen by insl'iecling the various ligures. that the rope orcable connected at one end to the eye bolt 2T carried by the l'ree endot the lever 2l, is tiret led to the drum LQ and passed therearound anydesired number oi turns, as indicated by the numeral ab. rlhe rope orcable 2S is then passed once around the grooved pulley il and from therethrough the rope guiding cross brace il to the grooved pulley 3G. Therope or cable passes around this grooved pulley 3G and extends throughthe opening formed in the rope guiding cross brace l2 from which it isled longitudinally out wardly tor permitting external power. such ashorses, oxen. a tractor or an automobile, to be connected to its treeend. lt is intended that this tree end 2S ot' the rope or cable 2S beprovided with a hool; 2S" tor per mitting the saine to be quicklyattached and detached to and from the external power. lt will be noticedthat Fig. 23 shows the rope or cable 2S shortened or ot reduced lengthto the rope or cable illustrated in Figs. l and 2. This manner ot'illustrating the rope or cable in Fig. 3 is tor the purpose of showingthe hook 28u that is intended to be carried by the free end.

rlhe operation olf the stump puller embodying` this invention is asfollows:-

It is intended that the stump puller be moved into proximity with thestump to be ordi-acted and with the sharpened projection and lever 2i inthe dotted line position shown in Fig. 3. The spi-ag bars El() are thenpivoted upon their supporting pins 3l to bring the tree ends intoengagement with the ground outwardly ol the opposite end ot the parallelside 'trames to the end carrying the lever rl`hese sprag barsl willprevent the stump puller from being Vforced or pulled away t'rom thestump to be extracted. 7Vitli the device in the position described, thetree end ot the rope or cable 2:5 is suitably attached to an externalsource olf power for the purpose ot causing the rope to be pulled uponto move the lever upon its supporting member, the axle il. for causingthe sharpe ed projection to be moved upwardly. This upward movement olthe projection will cause the stump to bo pulled or extracted i'rom theground. rl`he cranl; handle l-IB carried by the rotatable shalt Si maybe opeiined b v a person lor aiding in pivoting the lever 2st. yit willbe seen by this construction that great leverage may be brought o bearupon the stump to be extracted tor he purpose ot' performing the desiredoperation.

t is to be understood that the l'orm ot' this invention herewith shownand described is to be talien as the preferred example ot' the saine.and that various changes in the shape, size. and arrangement ot' partsmay be resorted to without dejar-ting from the spirit olE the inventionoi the scope olil the subjoined claim.

Having thus described the invention, I claim:-

ln a stump puller, a pair of side frames. a stump lifting` lever pivotedbetween said side trames, a winding drum journalled in said side trames.a rope wheel revolubly mounted between said side i'raines. a second ropewheel journalled in said side Vtrames. gearing connecting the drinn andsecond wheel. and a rope having one end connected to said lever, therope being wound several times about said drum and led it'rom the drumaround the first and second wheels and then forwardly and being providedwith a dralt hook at its forward extremity.

ln testimony whereof l allix my signature.
